VALVE LIFTER.

Application led February 24, 1926. Serial No. 90,412.

This invention relates to improvements in valve litters for use upon internal combustion engines contemplating the provision ot a support adapted to engage the head of the valve and the outer side ot the cylinder block above the valve chamber and having the lower end of an offset operating leverv pivoted to its upper side und adjacent the angle in the contiguration thereorl while a substantially L-shaped plate 'having' biturcated end portions receiving the operating lever at an appropriate point in 'its length between the upper bifurcation and an oli'set fork within its lower end and extending iuwardly toward the cylinder block for engagement with the spring cups upon the valve stems whereby a rocking movement and downward pressure exercised upon the support by the operating lever will cause the valve to be held in a desired position and the spring cup moved upwardly to facilitate the removal of the valve pin whereby the Avalve may be removed for inspection, regrinding or replacement.

The lower yend ot' the substantially l.- shaped plate and upper end of the fork have registering apcrtured portions therein for the reception or' fastening elements in the form of cotter pins therethrough whereby the fork may be adjusted to an appropriate point in its length to manipulate valve springs upon valves of various lengths.

lVith the above and other objects in view, the invention further includes the 'following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawing Figure 1 is a fragmentary elevation of a motor vehicle cylinder block illustrating the application and manner in which my invention is applied and used in conjunction therewith.

Figure 2 is a top plan view of the invention per se.

Figure 3 is a perspective of the fork per se.

Referring to the drawing 1n detail, wherein like characters of reference denote corresponding parts, the reference character indicates a fragmentary portion of a motor vehicle cylinder block illustrating the respective positions of a puppet valve 11, valve spring 12, valve spring cup 13 and valve pin 14:; all of the above being of the usual and well known construction and forming no part of the present application for Letters Patent but being merely shown and described for purposes oi illustration in bringing forward the novel advantages of.

the above entitled invention. p

The invention resides in the provision of a valve lifter, constituting a support embodying a pair of disks 15 and 16 arranged in horizontal and vertically disposed posi` tions respectively upon the head of a valve 11 and upon the outer side of the cylinder block 1() directly above the valve chamber w through while the lower ends o'f the plates' 21 receive the upper twisted end portion 23 of an offset fork 24 and which twisted portion `23 and lower ends of the plates 21 have a plurality of registering openings 25 provided therein for the reception of a Cotter pin 2G in lorder that the offset fork 2-1- may be set at a desired height, lengthened or shortened, as the case may be, for fitting and engaging the valve spring cups 13 upon the Various lengths of valves 11.

In 'the use and operation of the present invention it is clearly apparent and maniiest that the disk-lfrests upon the upper side of the cylinder block 10 and upon the head or' the particular valve to be removed or replaced while the disk 16 engages the outer side of the cylinder block directly above the valve chamber for creating a support and pivotal mounting for the operating lever 19 which being adapted to swing upon the respective pivots 20 and 22 between the apertured ears 18 extending upwardly from the reduced portion 17 associating the adj acent sides of the disks and between the upper ends of the plates 21 respectively in order that the same may be readily rocked to and fro thereon in the dotted line position as clearly illustrated in Figure 1 of the drawlfl ing for moving the oii'set fork Zei upwardly and downwardly for raising the valve spring cup 13 upwardly upon the valve stem and compressing the valve spring 12 whereby the valve pin let may be readily and easily removed precedent to the dotted line position of the invention as shown for releasing the valve spring cup i3 and valve l2 upon the upper end of the valve stem bushing in order that the particular valve may be removed from the cylinder block l0.

The invention is susceptible ot variousl changes in its torni, proportions and minor details of construction, and the right is herein reserved to make such changes as properly tall within the scope ot the appended claims.

Having thus described the invention, what is claimed is l. A valve litter tor use upon and in conjunction with internal combustion engines valves comprising a pair ot interassociated horizontally and vertically disposed disks adapted to be seated upon the head ot a valve and the corresponding outer side of the cylinder block, an operating lever pivotally mounted between the disks, and lifting means associated with the operating lever and valve mechanism.

2. A lifter for use upon valves within internal combustion engines comprising a pair ot horizontally and vertically disposed interassociated disks having spaced parallel upwardly extending apertured ears therebetween, a substantially l.-shaped operating lever having its offset end portion pivotally mounted between the spaced parallel apertured ears, and lifting means pivotally mounted upon the lever and adapted for engagement with the valve mechanism.

3. A valve litter tor use upon and in conjunction with internal combustion engines valves comprising a support constituting horizontally and vertically disposed interassociated disks adapted to rest upon the head of a valve and outer side ot the engine cylinder block and having upwardly extending spaced parallel apertured ears provided therebetween, a substantially L-shaped oper- Lef/27,95?

ating lever having its oti'set end portion pivotally mounted between the apertured ears, a pair of oitset companion plates pivotaliy mounted upon the opposite sides of' the operating lever, and means supported between the lower ends of the companion plates for engagement with the valve mechanism.

t. A valve lifter for use upon internal combustion engine valves comprising horizontally and vertically disposed interasseciated disks adapted to rest upon the top of a valve and outer side oi" a cylinder block and having upwardly extending spaced parallel apertured ears provided therebetween, a subs'tai'itially L-shaped voperating lever having its offset end portion pivotally mounted between the apertured ears, a pair of correspondingly shaped companion plates having their upper oiset ends pivotally mounted upon the opposite sides oit the operating lever, a substantially o'ii'set fork having its upper end mounted between the lower ends and inner sides ot the companion plates, and its opposite end being adapted tor engagement with the valve mechanism.

A valve litter for use upon internal combustion engine valves comprising horizontally and vertically disposed inter-associated disks adapted to rest upon the top ot a valve and outer side et' a cylinder block and having upwardly extending spaced parallel apertured ears provided therebetween, a substantially L-shaped operating lever having its oii'set end portion pivotally mounted between the apertured ears, a pair ot correspondingly shaped companion plates having their upper oiiset ends pivotally mounted upon the opposite sides ot the opera-ting lever, and an oitset :fork having an upper twisted and apertured end portion adjustably secured between the lower tree ends oi the companion plates for adaptability and application upon valve stems of various lengths.

In testimony whereof we aiiiX our signatures.
